According to Heavens Above, the ISS will be making two passes, one either side of launch, both with a negative magnitude, so assuming the Shuttle's on the same orbit, we'll have to wait and see.
Shuttle flies much lower! --> Shadow entry much earlier :-(

To quote Heavens Above :
Space Shuttle Mission STS-117
Atlantis is scheduled to launch at 23:38 UTC to the ISS. We will be posting
predictions once Atlantis is in orbit. Unfortunately, this time there will be no
opportunity to see the Shuttle and the external tank from Europe just after launch.
Atlantis will enter shadow just as it rises above the horizon as seen from British Isles.

Maybe we should ask them to launch at the start of the window....or hope for a scrub for tomorrow night!

Confirmation that they will target the middle of the window: 7:38:04 pm Eastern. (23:38:04 GMT)

When STS-105 launched we in England (probably some of Europe too, but I don't know that for sure) the orbiter and ET - about 20 minutes after launch- appeared much lower to the horizon than the ISS which had just completed a high pass, almost overhead from Yorkshire. I think we might struggle to see Atlantis tonight, but if the weather is clear over the next two nights we will see Atlantis and the ISS flying some distance apart on Saturday and then the next night, the stack after docking.

We have a thread for viewing opportunities, so let's keep the above out of the live update thread.

No constraints for launching at the middle of the window. Weather good, no issues.

When do they pressurise the COPVs? I was reading that there were concerns over pressurising them past 80% due to aging.
#208 by Svetoslav on 08 Jun, 2007 22:23
a ten-minute hold now...
#209 by eeergo on 08 Jun, 2007 22:23
20 minutes and holding.

Already done. They do that at L-4 days.

Is that to full, or 80%?

Fully pressurized. They do it in two stages, first to 80%, then to 100%.
